Scientists think the solar system formed around 4.6 billion years ago from a cloud of dust and gas known as a solar nebula. Gravity collapsed the material on itself as it began to spin. This formed the sun in the middle. The planets formed when rock joined together in clumps and became bigger and bigger. And thus, our solar system was formed. Hope this helped

Tom and Mary are riding a merry-go-round. Tom is on a horse about half way between the center and the outer rim, and Mary is on

iren2701 [21]

Answer:

Explanation:

Given

Tom is on half way between the center and the outer rim

Mary is on the extreme outer rim

Suppose $\omega$ is the angular velocity of ride with radius of outer rim be R

$\alpha =$ angular acceleration of Ride

At any instant both Tom and Mary experience the same angular speed

(b)Linear velocity at any instant

$v_{Tom}=\omega \times R$

$v_{Mary}=\omeag \times \frac{R}{2}$

Thus Tom has higher linear speed

$a_r=\omega ^2\times r$

$a_{Tom}=\omega ^2\times R$

$a_{Mary}=\omega ^2\times \frac{R}{2}$

Tom has higher radial Acceleration as it is directly Proportional of radius

List three unique examples of situations in your daily life where expansion and contraction occur.

Vera_Pavlovna [14]

When you put ice in the freezer, the water expands when in gets cold.
the sidewalks have cracks in them to make room for the expansion and contraction when it heats up and cools down.
as you drive a car, the heat from combustion causes metal to expand. when you turn the car off, the metal cools down and contracts
